Filed: 1972-08-25
Abstract: 1335789 Splitting machines FORTUNAWERKE MASCHINENFABRIK AG 25 Aug 1972 [3 Sept 1971] 39676/72 Heading B4B A device for guiding a band knife used e.g. for splitting, comprises a pair of guide plates 1, 2, the guide plate 1 being arranged to pivot relatively to the plate 2 about an axis K. The guide plate 1 is formed with a part-spherical surface 9 adapted to be urged by a spring 7 into contact with a corresponding surface formed on the head of a screw 8; the screw is adjustable in order to set the plates parallel with the side surfaces of the blade. Sintered metal jaws 3, 4 are secured to the plates 1, 2 and the pressure they apply to the band knife is determined by a spring 6 and the setting of the screw 8. Two sleeves 12, 13 are screwed to the plate 2 and cooperate with bores formed in the plate 1 in order to prevent the latter plate from twisting about the screw 8. In the modifications shown in Figs. 4 and 6, the spring 6 is replaced by a pair of tension springs 19, 20 connected to wedges 17, 18 adapted to abut against pins 15, 16 mounted in the plate 1. In this embodiment, the tilting of the plate 1 about axis K so as to increase the clearance between the jaws and the sides of the blade is prevented due to a self-locking effect of the wedges. In other modifications only one sleeve may be used or a single wedge may be arranged perpendicular to the direction of travel of the blade.

Filed: 1972-08-24
Abstract: 1371241 Wet separation of particles R G FULLER 24 Aug 1972 [19 Aug 1971] 39720/71 Heading B2H A helical concentrator for separating particulate matter entrained in a carrier liquid as a slurry comprises one or more stationary, downwardly inclined, one-piece, helical channels 1b, 1c, Figs. 4 and 6, having a smooth arcuate radial cross-section with a concave outer wall which terminates in an inwardly curving lip 9, Figs. 1 and 3, forming a smooth continuation in one piece with the outer wall. As shown in Fig. 4, the concentrator comprises two slurry separating channels 1b, 1c to which the slurry is supplied through feed boxes 4. Passageways 2a are located in the bottom of the channels at suitable positions in the path of the particles which separate out according to density so that the particles are diverted from the channel down collecting pipes 6. Liquid lost with the particles down the pipes 6 is replaced by wash water diverted from wash water channels 1, 1a to the slurry channels 1b, 1c via passageways 10 formed in a partition wall 13 between the adjacent wash water and slurry channels. The wall 13 may be of decreasing height from top to bottom of the helical path proportional to the decreasing volume of liquid entrained in channels 1, 1a as wash water is successively diverted into channels 1b, 1c. The passageways 10 may be provided with lips 11 to regulate the flow and control the discharge into channels 1b, 1c. Clear liquid is separated from the particulate matter by centrifugal force which causes it to rise up the inner side of the outer concave wall till restrained by lip 9, the inner edge of which may be terminated at a point such as to divert liquid back into the channel, e.g. lb, Fig. 1, at a point which will assist in the separation of particles and serve to replace some of the liquid diverted with the particles down the pipes 6. Alternatively the liquid may be diverted through the outer wall by passageways (2b) as necessary to collect floating particulate matter from the surface of the liquid, Fig. 2 (not shown), or to recover liquid from slurry channel 1b and direct it via a conduit 12, Fig. 6, into another channel 1c. Instead of a conduit being provided the two channels may communicate with each other via the passageways (2b), Fig. 7 (not shown). In Fig. 3, the lip 9 is bent through an arc in excess of 270‹ to collect floated particles. Interchanegable or rotatable weirs equipped with lips may be inserted in the passages (2a, 2b or 10) to project into the stream of liquid to be diverted and thereby regulate the flow thereof, Figs. 8 and 9 (not shown). Magnetic fields may be imposed to accelerate the collection of particles.

[Also in Group XXXVII] Connection between printed circuit members such as columns 14 and row 16 on opposite sides of an insulating board 10 is made by means of split conductive linings through holes through the board which may be joined by means of conductive plugs 30, Fig. 2. During manufacture an insulating board such as epoxy glass composition has apertures pierced therethrough. The entire board is then immersed in an electroless copper plating solution to deposit a thin copper coating 44 (not shown) over all its surfaces and line the hole. A punch is then put through the hole to make an aperture the shape shown in Fig. 7 and a resist is then placed on the board surfaces so that when the board is electroplated the plating is received only where the conductors are to be formed and at pads 18, 24. Finally, a dissimilar metal for example a lead-tin or rhodium electroplate is plated on the copper, the resist is removed and the deposited copper is dissolved away by etching. A light flash of copper may be applied to the deposited copper prior to punching as may the negative resist. The process may be carried out on the copper clad insulating board. Fig. 14 shows a construction in which pressure on button 82 causes a spring member 88 to open out on a fixed button in a member 78 to connect lugs 68, 70 together. Switch construction, Fig. 16.-A board carrying an aperture of the shape shown in Fig. 16 is coated in an electroless copper plating solution and a resist pattern 92 applied to the faces of the board. Next the whole is reamed to a single radius leaving alternate axial coppercoated and uncoated sections. The board is then electroplated to provide axial conductors in the holes and to provide surface contacts 94, 96 on those areas not covered by the resist pattern. The resist pattern is then removed and the deposited copper etched away. The switch rotor consists of spring-loaded rollers 106 to which connection is made through the springs and a wire 112 or by a printed circuit, the rotor surface extending into electrical contact with the shaft. A construction with only two diametrically opposite contacts is also described.
